Authorities said graffiti was spray-painted on the memorial in three spots. The messages were discovered Saturday.

The person responsible was caught on surveillance video, which was handed over to police.

Officials at the Liberty Memorial released this statement:

“While we certainly value everyone’s right to freedom of speech, we’re obviously disappointed that individuals would choose to express their views by desecrating one of our country’s most sacred memorials. We have already turned over security footage to the Kansas City Police Department to assist with their investigation and we will work swiftly to ensure that the north wall of the memorial is returned to its proper state.”
